BINDER-FRAME.

SPECIFICATION forming part of Letters Patent no. 739,552, datedSeptember 22, 1903.

Application filed February 9, 1903. Serial No. 142,479. (No model.)

To all whom it may concern: 7 Be it known that I, AUGUST H. LORENZ,citizen of the United States, residing at Chicage, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Binder-Frames, of which the following is a specification.

This invention relates to novel improvements in binder-frames of thekind employed for holding loose, leaves or sections; and its object isto provide a frame of simple and inand quickly adjusted to bind leavesor sections securely together or release them to permit of theirremoval.

With these and other ends in view the invention contemplates a framecomposed, essentially, of a back and two cover sections, a leverpivotallymounted on the back section and connected at its ends bytoggles with the coversections, and a screw operatively connected withthe levers for actuat ing the levers to adjust the coversectionsrelative to the back section.

' In the accompanying drawings I have shown one way in which theinvention may be embodied, and referring thereto-- Figure 1 shows theinside of a frame, partly in section, with the covers thrown back andbroken away. Fig. 2 is a sectional view on the line 2 2 of Fig. 1.-Fig.'3 is a sectional view on the line 3 3 of Fig. 1. Fig. 4 shows amodification of a detail of theinvention. Fig. 5 is a detail view on theline 5 5 of Fig. 1.

Referring to the drawings, in which like numerals of reference indicatecorresponding parts in the several figures, 1O designates the backsection and 11 12 the two cover-sections, which together constitute theprincipal parts, of the frame and may be constructed in any suitablemanner and varied in size, shape, and proportions, as desired. Thecover-sections are provided with inwardly-extending ends 13, which slideinside of the upturned ends 14 on the back section, and guide-plates I16 are fastened to theback section and overlap the cover-sections, asclearly shown inotally secured to the back section at or about I itsmiddle and has its ends connected by links 1818 with toggle-levers 1919,which in turn are connected at their outer divergent ends to thecover-sections adjacent to their ends. The links may be connected withthe toggle-levers in a variety of difierent ways, and the particularconstruction of devices for operating the lever 17 and toggles may bechanged in various ways. 1 preferably provide a single screw 20, whichis. mounted in bearings 21 of a suitable character and arrangedlongitudinally of the'frame between one end thereof and the leverl7,with its head 22 located, preferably, inside of the upturned end 14of the back section, so that access thereto can be had with anoperating-key through an opening 23in said end. A collar 24 is mountedto travel on the screw, and

the converging ends of the levers l9 and the outer end of the link 18'are suitably connected with the collar to be actuated as the collar ismoved back and forth by the turning of the screw. I have shown, Fig.3,the collar provided with a pin or post 25 to form a pivot for thetoggle-levers and link, and this pivot is arranged on the underside ofthe collar; but I do not limit myself to this construction andarrangement, for obviously the levers and link may be connected with thecollar on'its upper side and in other ways than that shown withoutdeparting from the invention. In Fig. 4: I have shown another way ofconnecting the collars with the levers and link, the difierence beingthat the levers are connected to the collar atits sides and the linkisconnected to the collar on its top. At the other end of the frame thetoggle-levers 19 are connected with the link 18 by a pin 26 or in anysuit- The movement of the operative parts of the invention heretoforedescribed will be apparent from the description and the drawings, and itwill be observed that the operation is very simple and that the pressureapplied can be increased or diminished, as desired. When the screw isturned, the actuating-lever 17 will be swung on its pivot to communicatea contractile or expansive action to the toggles at each end of theframe. As the toggles are actuated simultaneously and are guided in thesame plane, the side sections will be moved correspondingly. The leverdevice for actuating the side sections can be operated to produce agreater or less pressure upon the interposed leaves, as desired, andthis pressure may at all times be sufficient to hold the leaves inproper place and prevent their disarrangement or dislodgement.

The leaf-rests comprise telescoping tubes 30 and pins 31, attached tothe cover-sections, and are preferably arranged with the tubes and pinsalternating on each section.' The covers 32 are connected with thecover-sections in any suitable manner.

My improved binder-frame can be manufactured inexpensively and in agreat variety of sizes and shapes for difierent purposes,and itcomprises only a few parts, which are arranged to operate in a simpleand efiective manner.

I do not limit myself to the particular construction and arrangement ofparts nor to the details herein shown and described, for obviously manychanges can be made without departing from the spirit or sacrificing theadvantages of the invention, and I reserve the right to make all changesas fairly fall within the scope of the invention without departing fromits principles.

While the invention isprimarily intended as a binder for loose leaves,it is apparent that the uses of the invention are not limited in thisparticular, and it may be employed for holding sections, signatures,newspapers,

magazines, or, in fact, any articles which are 2. A binder-framecomprising a back section and two cover-sections, a lever pivoted to theback section at or about its middle, toggle-levers at the ends of theframe and having their diverging ends pivotally connected to thecover-sections and their converging ends connected with said lever, anda screw for operating the levers.

3. A hinder-frame comprising a back section and two cover-sections, alever pivotally mounted on the back section, a toggle at eachv end ofthe frame having its diverging ends pivotally connected to the coversections, links pivotally con nectin g the converged ends of the togglesand the ends of the links, and means for operating said levers.

at. A binder-frame comprising a back section and two cover-sections, alever pivotally mounted on the back section, a toggle at each end of theframe having its diverging ends pivotally connected with thecover-sections, links connecting the converged ends of the toggles andthe ends of the lever, and a screw for operating said levers.

5. A binder-frame comprising a lever pivotally mounted on the backsection between the ends of the frame, toggles connected with thecover-sections and the ends of said lever, and a screw arranged betweensaid lever and one end of the frame for operating the levers.

6. A binder-frame comprising a back section and two cover-sections, alever pivotally mounted on the back section between its ends, a toggleat each end of the frame pivotally connected to the cover-sections andone end of said lever, and a screw arranged between said lever and oneend of the frame and connected with the lever for simultaneouslyoperating the toggles.

7. A binder-frame comprising a back section and two cover-sections, alever pivotally mounted on the back section, a toggle at each end of theframe pivotally connected with the cover-sections and with the lever, ascrew arranged between the lever and one end of the frame, and a collartraveling on said screw and connected with the lever.

8. A binder-frame comprising a back sec- ICC tion and twocover-sections, a lever pivotally mounted on the back section, a toggleat each end of the frame pivotally connected to the cover-sections andto the lever, and a guide on the back section for each of said toggles.

9. A binder-frame comprising a back section and two cover-sections, alever pivotally mounted on the back section, a toggle at each end of theframe having its diverging ends pivotally connected with thecover-sections and its converged ends pivotally connected with thelever, a slotted guide-plate for one of said toggles, a screw foroperating the levers, and a collar traveling on the screw and 1connected with the converged ends of the other toggle and with saidlever.

AUGUST I-I. LORENZ.
